Is there a console command for brightness?

Is there a console command for brightness?

If there is , what are the range of values that it can have?

I’m trying to make a menu that uses console commands for the visual options. For some reason google is not giving me much help with the brightness option.

I saw that there used to be a command “brightness” where you could used + or - or put in a value from 0-1 but when I tried it, it didn’t do anything.

Thanks for any help you can give me!
